The Stip-scan
is the first generation of a new type of spectroscopic
sensor that measures wastewater using a light spectrum from
190 to 720 nm. In addition a new patented settlement phase
can be used to provide an on-line measurment of Total
Solids and SVI
(Sludge Volume Index).
Recent
developments in spectral measurement presents possibilities
for measuring in-situ a wide range of parameters simultaneously
such as NO3, SAC(UV 254), COD, and TOC. However interfering
effects of turbidity, colour and "overlapping" absorbtion
spectra must be taken into account for accurate and reliable
measurement, especially in a changing wastewater matrix. The
Stip-scan
solids settlement phase enables
such potential interferences to be accomodated and results
in greater precision and confidence with measured results.
